This invention relates toy combination lcrayon holders and erasers and in particular to a device oithis character which is especially adapted for use in schoolrooms and While lecturers use chalk for explanation purposes; Yj i Y A particular object of the invention'is to provideA a single implement 'which mayy be used by a teacher when Writing upon a blackboard for holding chalk and an eraser so that during an illustrated discussion, if an error is made, the necessity for interrupting the discussion and inding an eraser Will be eliminated.

Another particular object ot the invention is to provide in combination, an eraser and chalk holder Which will be convenient to use and Which Will prevent the soiling of 'the hands during the use of the chalk,

A still further object of the invention is to provide an eraser in combination with a chalk holder which may be effectively used and Which will eliminate the necessity for using a chalk lad-en eraser which has been used to clean the entire blackboard, as it is Well known that erasers in common use soon become impregnated with chalk particles and, with little use, cover the fingers with chalk, which is unpleasant to the touch.

To enableV others skilled in the art to fully comprehend the underlying features of myV invent-ion that they may embody the same in the various modifications in structure and relation contemplated, a drawing depicting a preferred form has been annexed as a part ot this disclosure andin such drawings, similar reference characters denote corresponding parts throughout all the views, of which,

Figure l is a view in elevation of my improved chalk holder and eraser, showing a piece of chalk therein in position to be used.

Figure 2 is a view in sectional elevation showing the connection of the eraser With the body ot' the implement and the attachment thereto of the chalk holding sleeve, there being shown positioned therein, a piece ot chalk ready for use.

Figure 3 is a modified form of chalkjacket used separately andpreferably made of paper which can be used to cover a single piece of i927. serrano. 173,140.,

which fisimade offelt and' which may be in any shape desired. It yofcourse bein'gunder- `stood that While I have shown this inthe f' nature of a y rectangle the eraser may be square or round toV suit the conveniencerof `the user., The lower 'end of the body 5 is 4Vprovided with a headed pin 9 which .entendsthrough the longitudinal slots 10L formed in a1ohalk holding lsleeve l1, the slot fat 'its upper end being disposed transversely fa short distance to provide a lock whereby theholder :11 can- ,Y

Y i VItis evident therefore, I have 'provid-f, ed an improved crayon holder and eraser` :holder which willeliminate waste'of time by the instructor in' looking about for an leraserA when a mistakeis made and one also, which will prevent the fingers from becoming soiled. Y
